MANIFOLDING ENVELOPES.

Application filed December 5, Q1921. Serial No. 520,086.

To aZ-Zwhomz't may concern: Y

Be it known that we, J osErH H. BONNE- VILLE and HARoLn S. BARNES, citizens of the United States, residing at Stamford, inthe county of Fairfield and State ofConnecticut, and Yonkers, in. the county of lVestchester, and State of'New York, respectively, have invented new and useful Manifolding Envelopes, of which the following is a specification. i

It often happens that in writing, typing or otherwise marking inscriptions upon envelopes or other enclosing devices, it may be desired to effect reproductions of a single inscription so limited in number that printing or stenciling them in the customary ways is unprofitable. The present invention provides a system and method by which a plurality of addresses or like inscriptions may be produced by a single markingjop eration, with existing methods.

Means by which our invention may be carried out is illustrated in the accompanying drawing, in which Figure l is a perspective view of an envelope arranged in accordance with the present invention; Fig. 2 shows in perspective a set of these envelopes partly assembled in preparation for manifolding; Fig. 3 is a transverse sec tion through the assembled or nested envelopes; and Fig. 4 is a view, similar to Fig. 2, of a set of envelopes of another form, as they would appear in being assembled for manifolding.

To consider a particular application of the invention, let it be assumed that a set of envelopes, appearing in the drawing as four in number, are to receive the same inscription. These may be for use in connec* tion with an advertising undertaking, in which a series of so-called follow-up communications are to be mailed under the addressof one person; in notifyingmembers of an organization of periodic meetings;

same individual; or for many other uses which will suggest themselves. In accordance with this invention, a set 10 of the proper number of envelopes is so formed as to permit them to be assembled in a series. Preferably, they are arranged to nest one within another, being of gradually decreasing superficial dimensions from the outer enveto which the address is directly apa substantial economy overplied, to the inner 12, as shown in Figs. 2

and 3.

Each, of these envelopes is of that well-known form in which, by gummed flaps overlapping at the back, they are closedv along three edges 13, there being a free flap late permit the contents to be inserted and thereafter enclosed byv the sealing of this flap The front wall 15 of eachlenvelope, the outer surface of which is to'bear the address, carries over a suitable area-16' a manifolding substance, as a carbon-pigment, save the inner, from which it may be omitted. This pigment may be applied in any convenient manner, as directly to the paper of the envelope, or upon tissue attached thereto, lying with its active face in contact with the. address-receiving surface of the next envelope of the set. When thus assembled and the address is typed or otherwise impressedupon the front 15 of the envelope 11, it will be transferred by each succeeding layer of pigment to the receiving surface beneath it, so that by one operation the entire set of envelopes will receive their inscriptions. If these are to be employed for the purpose first stated-the mailing of advertising letters-they may be removed from the nested set one by one'as the communications are sent,- and if one remains unused when a responsive order is received, this may be employed for the acknowledgement.

It is not essential to the invention that the envelopes which are to be assembled for the manifolding process sh all for their nesting be closed along three edges, as in the form just described. They may, instead, be of the type appearing'at 18 in'Fig. 4, which, while giving the appearance of being sealed or constituting first class postal matter, is capable of being opened after closure for inspection-by post-office officials by drawing out an unsealed envelopes, prior to the insertion of. the, contents and their closure, have the main flaps 20 and auxiliary flaps 19 projecting from the body substantially in the plane of the flap 19 at one end, Theseaddress-receiving wall 21. This leaves two I edges closed at Inent of jemzelopesiandi thearnani'foldi prece'a dure may be as'already described, save-in this case it should be noted that no graduation in size isnecessary to effect; the nest ing. 7

It will be evident, in Whatever manner our invention is practised, that, operating with. in the limit of sufliciently clear inanifolding, say ten copies, it will efl'ecta marked saving overthe laborious addressing of each copy separately, and also overthe; preparing of i a special reproducing,instrurnntality for each address, as why chara ers 'forpr nt g,
